By the end of 2014, 7,000 people had completed the remarkable training designed by award-winning psychologist Steve Wilson to qualify for the designation of Certified Laughter Leader(tm). This accomplishment is his major contribution to the field of mind-body science, by creating a therapeutic method of systematic exposure to true mirthful laughter in a supportive environment, that has been found to be credible by professional organizations of nurses, psychologists, counselors, activity therapists, health educators, marriage & family therapists, and social workers. The roots of this method go back to ancient practices, biblical prescriptions, and modern science. The method reflects a 40+ year career in psychology and a philosophy of happiness through living with a positive sense of urgency, summed up as "Don't Postpone Joy".
